The halogens are the elements that are apart of group 17 on the periodic table. This group consists of the elements, Fluorine, Chlorine, Bromine, and Iodine. All of these elements are non-metals and very reactive with other elements, especially those of the group 1 Alkali metals. The reason for the halogen's high reactivity lies in their outter shell. They only need one more electron to have a full outter shell of eight electrons. As a result, the halogens have some of the highest electronegativity measurements of all of the elements.
Halogen Properties
All of the halogens have these properties in common: they have small radii relative to the other elements, they have relatively low boiling points and they are highly reactive. As you go down the group you will find that the boiling point goes down, the elements become darker, and they become less reactive to othe elements.
Only found naturally as compounds.
can form binary compounds with hydrogen.
Halogen Compounds
Formed when halogens combine with another substance. As mentioned above, Halogens can form many compounds with many different elements. Because of their high reactivity, Halogens are only found naturally within compounds. They can form substances such as acids, such as Hyrdogen Flouride(HFl), or salts when combined with the alkali metals. Interhalogen Compounds are the result of two halogens that have combined with each other. Examples of such compounds are Iodine Monochloride(ICl) and Chlorine Monoflouride(ClF).
